pastonly not working correctly

I really like the simplicity of this plugin. Thank you for writing it.
I list upcoming and current events in one column and past events in a separate column. However, the show_events=”pastonly” short code displays both past and current events. I’m using version 0.4.0 which is the latest version on ww.wp.xz.cn.
